These are the other equations I've balanced. I need help with one. AgNO3 + K2Cr2O7 --> double replacement AgNO3 + K2Cr2O7 --> AgCr2O7 + K2NO3 Please tell me if I've balanced these right. Br2 + NiI3 --> single replacement, element is a non-metal Br2 + NiI3 --&g...

Thank you very much DrBob222, if I ever get stuck again, I'll be sure to ask you, but before that I'll try to figure out the problems myself as a challenge. Thank you

DrBob222
DrBob222 I am kind of stuck with the balancing stuff, and I already had send the post, did you not read it?

Chemistry
Also for this equation: BaCl2 + Pb(NO3)2 I know that there is an invisible 1 infront of Ba, and that Cl is 2, but say if there wasn't that 2 there, then would there be an invisible 1 coeffient infront of Cl?

Chemistry
DrBob222 I also want to ask you something which was confusing me like a nightmare all that time, and today I realized it. For ex. C6H12O4 + 7O2 --> 6CO2 + 6H2O This equation here is balanced. But on the right side the coefficients 6 and 6 equal up to 12, isn't the left ...

Chemistry
BaCl2 + Pb(NO3)2 Could you also show me how to do the double replacement thing. The obly reactions I am getting how to do are synthesis and combustion. I need to practise alot on the other ones. Could you please show me step by step how you balance this equation. Thank you ver...

Chemistry
The decomposition is a bit harder for me than the rest. I looked over the examples in my book tons of times, but I still don't get it. Rb2O --> Decomposition Rb + O2 I don't know what to do rest.

Chemistry
C) C2H6+O2 --> Combustion Products: 2 molecules of Carbon dioxide, 3 molecules of water C2H6 + 4O2 --> 2CO2 + 3H2O D) C6H12O4 + O2--> Combustion Products: 6 molecules of Carbon dioxide, 6 molecules of water C6H12O4 + 7O2 --> 6CO2 + 6H2O sorry I forgot to mention ho...

Chemistry
A) Al + F2 --> Synthesis Products: 2 molecules of aluminum fluoride 2Al + 3F2 --> 2AlF3 B) K+O2 --> Synthesis Products: 2 molecules of Potassium oxide 4K + O2 --> 2K2O C) C2H6+O2 --> Combustion Products: Carbon dioxide, water C2H6 + 4O2 --> 2CO2 + 3H2O D) C6H...

Chemistry
I'll try to write quickly and post what I've done on here, but please sir stay.
